Revision history [back]

As Frank has noted, at WaterAid we use both the WagTech and the DelAgua options. Both are good sets of kit and are very similar in many respects. However we have found the biggest constraining factor is which company has the best supply chain of the consumable items within the country that we are using it. This would go for any technology choice, so I would strongly recommend that that you thoroughly investigate which of these options provides the best consumable supply chain for your purposes.
